COPD and swimming
I am a 63 year old former smoker and firefighter. I have COPD which limits the elasticity of lung tissue. I have built myself back up to swimming a mile a day. I have just discovered T.I. and I am trying to make adjustments in my style to make my swimming easier.
The problem is that I have no "reserve" for holding my breath for any length of time. I've tried meditation, deep breathing prior to swimming and just about anything else that I can think of including the Power Lung. After less than 10 seconds, I'm out and it's difficult to build up a cushion again.
Is there any workable exercises or tips that I can use to increase my lung power? Any help would be appreciated. If this has been covered before, I apologize.
